我们提出了一个配备智能钻取的数据探索系统，这是一种新颖的运算符，用于交互式探索关系表以发现和总结“有趣”的元组组。每个这样的元组组都由一条规则表示。例如，规则 (a, b, ★, 1000) 告诉我们有一千个元组，第一列中值为 a，第二列中值为 b（第三列中为任意值）。智能深入分析向分析师提供了一系列规则，这些规则一起描述了表中有趣的方面。分析师可以定制有趣的定义，并且可以交互式地对现有规则应用智能向下钻取以探索表的该部分。在演示中，与会者将能够使用配备智能钻取功能的数据探索系统，并将能够将智能钻取与传统钻取进行对比，以了解各种兴趣度度量和资源限制。
We present a data exploration system equipped with smart drill-down, a novel operator for interactively exploring a relational table to discover and summarize "interesting" groups of tuples. Each such group of tuples is represented by a rule. For instance, the rule (a, b, ★, 1000) tells us that there are a thousand tuples with value a in the first column and b in the second column (and any value in the third column). Smart drill-down presents an analyst with a list of rules that together describe interesting aspects of the table. The analyst can tailor the definition of interesting, and can interactively apply smart drill-down on an existing rule to explore that part of the table. In the demonstration, conference attendees will be able to use the data exploration system equipped with smart drill-down, and will be able to contrast smart drill-down to traditional drill-down, for various interestingness measures, and resource constraints.
